To all wlw/1i it may concern:

citizen ofthe United States, residing at Cliicago, in tlie county of Cook and State of Illinois, have invented certain new and use ful Improvements in Six-VVheel Trucks, of which the following is a specification.

This invention relates to an improvement in six-wheel trucks, and has for its ,object to provide an improved form of truck construction.

Hitherto in car construction, 'especially with reference to freight cars, the possible loading capacity has been limited 'to' less than one hundred thousand pounds. Owinq; to the use principally of the four-Wheel truck, the unit Weight carried by each Wheel and the corresponding` crushing eiect observed upon the ivlieel serve to limit the ssible loading capacity of the oar. By v'utiliz-A ing a six Wheel truck construction, the total Weight at each end of the car may be clistributed between the six Wheels, "thus `in-fcreasing tlie'fpossible total loadcapacity'.'

The use" of thesix-'Wlieel truck. hitherto,

however, in freight car constructionlias! been impractical, 'oiving to thelengtti oi wlieel base' required and the consequent non-A rigidity and greater wearing effectv upon the 'rail in rounding curves', etc. `By. iny 11nprovedconstruction I aingenabled to provide a six-wheel truck and approximatelyfonly '7 foot wheel base, ivliich-is vcoinpactand 'comparatively -rigid in construction and readily assembled or disassembled. as Willbe -apparent. I secure 'this result by an iin- -proved'forin of equalizer bar supported'below and by the journal boxes, the space between adjacent journal bqxesrbeing practically unfilled, except for the springs extendingr betweenthetruck side raineand tlie equaliser' bar.4

In `ne ordinary form of equalizer bar 1t is customary to incline portions of tlie saine permit the ends thereof to rest on topl of the? journal boxes. Inasrnuchas it has been found. highly desirablejtolocate thespring" adjacent each extremity upwardly, so asv to seats of tlie equalizer bar and truck side frame Aat a point approximately one-third of' tlie distance 'between adjacent journal boxes, it vwill ,be readily apparent that the upwardly inclined' portions of the conventional equalizer bar will operate to prevent seatingr of the springs at such apointinclose Vdistelfnze between adjacent journal boxes will Be it known that I, EDWARD Poseen, a.-

Y Like numerals and letters refer to like ele- 'iiints 'throughj out. .the drawings, wherein- A indicates-what I term my top casting,

l 4comprising'.'-'tlie' transom bars 20, joined by tlie cross bolster .21, integrally formed theren f with. The transom bars are preferably orm'ed Tof -shaped cross section, as shown clearly in Fig. 5.l The'cross bolster is preferaloly formed of channel-shaped cross tion, as' indicated in Figs. l and central plate' 22 is carried by the cross' bolster 21, and is providedivitli the usual central socket 23 and the dished-out portion loe '24, Brackets 25 project outwardly from' one of the transoin bars 2G.. EachA of the transom'bars is .provided with tlie outwardly ofthe ends of Fig. 5.

'A side fram-e30 is located oneacli sido; if the truck. This side ramejis preerablyV extending; end flanges Q6 and the down: wardly extending flange 2T located inwardly'- les tlie transom bars, as showim. u

of' integral construction and'v isprovidedyip with depressed portions lfingite snrv proximity'to one journal box-that. is, the

A against the inner secured the ends 26 of the transom'bars. lhe downwardly extending flanges 27 abut side of the side frame, and are riveted or otherwise secured thereto. Thos-ide frames 30 are also provided with the depressed po tio-ns 32 at their extremities, in which are seated and secured Jthe ends oit the extremities of the end beams 35, formed of angle iron, as shown. These end beams have the side and top of their extremities riveted or otherwise suitably secured to the ends ot' the side frames. f These side frames are provided with downwardly extending jaws 36, which forni the apertures 37 located on cach side. Formed on the under side of the side frame are the .spring seats 38. l

Journal boxes 40, of conventional interior construction, are carried at the extrem-v ities of 'the axles el extcriorly of the wheels 42, as shown in Fig. 7. These journal boxes are provided `with continuous flanges 48, :Formed on their sides and top, and with dfnvnwardly depending ears 44 at their bottorn portion. Extending between the earsin the construction shown in Figs. l to 9 inclusive-is the integrally formed support ing member 4:5. rllhe jaws 3G of the Side frames 30 are adapted to tit on and closely embrace the sides lof the journal boxes 40, being seated between and held against lateral movement by the flanges 43, as shown in Fig: 2 of the drawings. This construction will permit relative up and down 1novenient of the Side frame with respect to the journal boxes, but relative lateral movement will be prevented, as will be apparent.

Equalizer bars B extend between adjacent journal boxes, as shown in Fig. 2, and are constructed with side lianges 50, connected by the top flange 5l, downwardly extending between said side flanges, as indicated by 52, and terminating in the approximately horizontal portion The sides adjacent to each' extremity are curved downwardly, as indicated by numeral 52, on their upper surface and are cut out at flush with the under surface of the flange portion A. groovef'ir depression 56 is formed in the under surface of Athe sides 55 and flange portion 53. The construction at the other extremity of the equalizer B is similar, except that one oi.' the sides 50 in` stepped, as indicated by the numeral 57, and the portion 52 of thetop flange 5l is curved upwardly shown in the drawings. The supporting member 45, carried between the cars lll, is slightly rounded, as indicated by numeral 5S, and is provided with the up'wanlly projecting,r rib 59 adapted to lit in the groove 5G ol' the equalizer bnr B. spring seat lill is prm'idcd'in the upper surface of the equalizer bar B.

l'vhen the device is assembled, the in- Jendine ears of the 'ournal box.

infettati stepped extremities 5'? of adjacent equalizer bars B are interfitted, as shown in Flg. 7,

'atsthe central journal box, the other eX- tremity. being formed ot' a Width approximately equal to the distance between the e groove 5G in the under surface at the eX- treinity of the equalizerbar is adapted to lit on the rib 5S). Springs 6l are, located between the under surface of the side frame 30 and the upper surface of the equalizer bar, the extremities of said springs being located in the seats and 38. As in the construction ldescribed and claimedI inrniy prior Patent, No. 979,033, I prefer to locate each pair of corresponding seats 38 and 60 at a point inwardly of the *outer axle 4l, a distance equal to one-third the distance between adjacent axles, whereby approximately two-thirds of the weight to be borne by each equalizer bar will be carried by the outer journal box, and the central journal box will support a like' total weight, supporting one-third of the total amount carried by each equalizer bar.

In the modification shown in Figs. l() to 12 inclusive, the construction is similar to that shown in the preceding gures, ex-

cept as to the supporting of the equalizerA bars and their construeti'on.- In the modilication the journal boxes 40 are provided with the downwardly depending ears 44:, apertur'ed at'fll to receive a removable pin 70. The equalizer bars B are formed with the side flanges 50 and the top flange 51 carrying on its upper surface the spring seat G0. The equalizer bars B are provided with the circular ond portions 71, centrally apertured at 72. One extremity of each equalizer bar B is instepped or reduced, as indicated' at T3, these instepped ends of adjacent parts of said equalizer bar being adapted. to interl'it, as shown in Fig. l1, when in assembled position. The pins are inserted through the apertures 72 in the ends of the equalizer bar., and serve to support the same in detachable relation to the journal boxes. In other respects the construction issimilar to that shown in the preferred form.

lt will be apparent from the above description and amrompanyiug drawings that l have provided a simple, compact, and economical six-wheel truck, easily assembled, und ot sti-one' construction.

While l have described and shown my device with more or less particularity, I do not wish to be unduly restricted to Such de,- scription or showing' beyond the scope of the appended claims.
